Optex SL-200QDM SmartLine Professional Outdoor Photoelectric Quad-Beam Detector with Automatic Transmit Power Control, 200' Range

Protect perimeter assets with a dependable, low-maintenance beam detector engineered for real-world conditions. The Optex SL-200QDM SmartLine photoelectric beam detector combines quad-beam detection and dual modulation to cut nuisance alarms from birds, foliage and electrical interference while delivering a 200' outdoor detection range for effective perimeter monitoring. Automatic Transmit Power Control (A.T.P.C.) continuously adjusts beam output to compensate for fog, frost and signal noise, reducing missed alarms and maintaining reliable surveillance performance. Built for installers, the SL-200QDM features a Sniper ViewFinder, Alignment Sound Assist and BAU-4 compatibility so a single technician can quickly align long-range beams, saving time and labor costs. With 4-channel frequency selection and IP65 weather protection, it integrates easily into high-security systems and multi-beam networks without compromising uptime. Ideal for perimeter security, facility monitoring, and critical-site surveillance, the Optex SL-200QDM provides robust, scalable detection that minimizes false positives and simplifies maintenance. Specify this detector for commercial gates, fence lines and outdoor compounds — contact your security integrator to include the SL-200QDM in your next perimeter protection design.
